Abstract

The resonant states in the key reaction⁸Li(α,n)¹¹B for the inhomogeneous Big Bang Models were studied experimentally through the⁹Be(α,p)¹²B reaction at 64 MeV. This reaction is found to excite all the resonances of interest in¹²B. The most crucial resonant state at 10.572 MeV in¹²B (0.572 MeV above the α threshold) was found to have Γ_tot≤20±10 keV and J_π=(1^-), suggesting that the S-factor of the (α,n) process should be larger than that obtained before.
